[0002] The cutting traction machine is a device used for integrated material conveying and cutting operations. It is widely used in the processing of flexible materials such as film, paper, and fabric. Its core function is to achieve stable material traction and precise cutting, ensuring production continuity.

[0003] The existing cutting traction machines also have some problems, such as the top conveyor belt being mostly a fixed structure, which cannot adjust the distance between it and the bottom conveyor belt, and can only be adapted to materials of a single thickness, making the cutting traction machine not very versatile.

[0004] Therefore, a cutting and traction machine is urgently needed to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a cutting traction machine to solve the problem of traction in cutting traction machines.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A cutting traction machine, comprising: Bottom conveyor belt; The top conveyor belt is vertically mounted on top of the bottom conveyor belt. The top conveyor belt adjusts the distance between itself and the bottom conveyor belt through lifting and lowering to accommodate materials of different thicknesses to be cut, and together with the bottom conveyor belt, clamps and pulls the materials to be cut along the material conveying direction. A cutting blade is located downstream of the material conveying path of the bottom conveyor belt and is used to cut the material after it has been pulled by the bottom and top conveyor belts.

[0007] As a preferred embodiment of a cutting traction machine, it includes a guide member connected to both sides of the bottom conveyor belt, with the top of the guide member extending to the top conveyor belt, and both sides of the top conveyor belt slidingly engaging with the guide member.

[0008] As a preferred embodiment of a cutting traction machine, the guiding component consists of a plurality of guide posts, which are arranged vertically at intervals along the material conveying direction of the bottom conveyor belt. Guide holes are provided on both sides of the top conveyor belt corresponding to each guide post, and the guide posts pass through the guide holes and slide in cooperation with the guide holes.

[0009] As a preferred embodiment of the cutting traction machine, a synchronization component is also included, which is disposed between the bottom conveyor belt and the top conveyor belt, and the synchronization component is respectively connected to the drive shaft of the bottom conveyor belt and the drive shaft of the top conveyor belt to ensure that the conveying speeds of the bottom conveyor belt and the top conveyor belt are kept consistent.

[0010] As a preferred embodiment of a cutting traction machine, the synchronization component includes an upper main gear, an upper auxiliary gear, a lower main gear, and a lower auxiliary gear. The upper and lower main gears are coaxially and rotatably mounted on the guide post. The upper auxiliary gear is fixedly sleeved on the end of the drive shaft of the top conveyor belt and meshes with the upper main gear. The lower auxiliary gear is fixedly sleeved on the end of the drive shaft of the bottom conveyor belt and meshes with the lower main gear. When the upper main gear moves up and down along the axial direction of the guide post with the top conveyor belt, it maintains a meshing state with the upper auxiliary gear to ensure synchronous conveying of the bottom conveyor belt and the top conveyor belt.

[0011] As a preferred embodiment of the cutting traction machine, it also includes an auxiliary wheel. The cutting blade is provided with brackets on both sides. The side of the bracket is provided with an opening adapted to the auxiliary wheel.

[0021] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0022] In one embodiment of this utility model, such as Figure 1-6 As shown, a cutting traction machine is provided, comprising:

[0023] A cutting and traction machine includes: a bottom conveyor belt 1, a top conveyor belt 2, and a cutting blade 3. The top conveyor belt 2 is vertically mounted on top of the bottom conveyor belt 1. The distance between the top conveyor belt 2 and the bottom conveyor belt 1 is adjusted by its lifting action to accommodate materials of different thicknesses to be cut, and together with the bottom conveyor belt 1, it clamps and pulls the material to be cut along the material conveying direction. The cutting blade 3 is located downstream of the material conveying path of the bottom conveyor belt 1 and is used to cut the material after it has been pulled by the bottom conveyor belt 1 and the top conveyor belt 2.

[0024] The cutting and traction machine provided by this utility model, through the adjustable top conveyor belt 2, can flexibly adjust the distance between it and the bottom conveyor belt 1, thereby precisely adapting to materials of different thicknesses to be cut. This not only improves the versatility of the equipment but also ensures the stability and accuracy of the material during the traction process. Simultaneously, the cutting blade 3 is positioned downstream of the material conveying path of the bottom conveyor belt 1, allowing the material to be immediately cut after being gripped and tractioned by both the top and bottom conveyor belts 2 and 1, further improving production efficiency and cutting quality.

[0025] In this embodiment, the lifting function of the top conveyor belt 2 and the cutting blade 3 can be achieved by installing a cylinder. In this embodiment, a carrier plate 12 can be installed to mount the bottom conveyor belt 1, the top conveyor belt 2, and the cutting blade 3. Additionally, multiple sets of cutting traction machines can be installed to form a multi-station system.

[0026] The cutting traction machine includes a guide component 4, which is connected to the two sides of the bottom conveyor belt 1, and the top of the guide component 4 extends to the top conveyor belt 2. The two sides of the top conveyor belt 2 are slidably engaged with the guide component 4.

[0027] Furthermore, the guide component 4 is composed of several guide posts 401, which are arranged vertically at intervals along the material conveying direction of the bottom conveyor belt 1. Guide holes are opened on both sides of the top conveyor belt 2 corresponding to each guide post 401, and the guide posts 401 pass through the guide holes and slide in cooperation with the guide holes.

[0028] When the material to be cut is placed on the bottom conveyor belt 1, and the top conveyor belt 2 descends to clamp and pull the material together with the bottom conveyor belt 1, the guide component 4 ensures that the top conveyor belt 2 maintains stable linear motion during lifting and pulling, without any deviation or shaking. This is because the precise sliding fit between the guide post 401 and the guide hole provides accurate guidance and constraint for the movement of the top conveyor belt 2. Moreover, this structure is simple and easy to maintain, with minimal wear on the guide post 401 and the guide hole, resulting in a long service life and reduced equipment maintenance costs.

[0029] The cutting traction machine also includes a synchronization component 5, which is located between the bottom conveyor belt 1 and the top conveyor belt 2. The synchronization component 5 is connected to the drive shaft of the bottom conveyor belt 1 and the drive shaft of the top conveyor belt 2 respectively, so as to keep the conveying speed of the bottom conveyor belt 1 and the top conveyor belt 2 consistent.

[0030] Furthermore, the synchronization component 5 includes an upper main gear 501, an upper auxiliary gear 502, a lower main gear 503, and a lower auxiliary gear 504. The upper main gear 501 and the lower main gear 503 are coaxially and rotatably mounted on the guide post 401. The upper auxiliary gear 502 is fixedly sleeved on the end of the drive shaft of the top conveyor belt 2 and meshes with the upper main gear 501. The lower auxiliary gear 504 is fixedly sleeved on the end of the drive shaft of the bottom conveyor belt 1 and meshes with the lower main gear 503. When the upper main gear 501 moves up and down along the axial direction of the guide post 401 with the top conveyor belt 2, it maintains a meshing state with the upper auxiliary gear 502 to ensure the synchronous conveying of the bottom conveyor belt 1 and the top conveyor belt 2.

[0031] When the cutting traction machine starts, the drive shafts of the top conveyor belt 2 and the bottom conveyor belt 1 begin to rotate, driving the upper auxiliary gear 502 and the lower auxiliary gear 504 to rotate respectively. Since the upper auxiliary gear 502 meshes with the upper main gear 501, and the lower auxiliary gear 504 meshes with the lower main gear 503, and the upper main gear 501 and the lower main gear 503 are coaxially mounted on the guide column 401, a stable transmission system is formed. As the top conveyor belt 2 moves up and down along the axis of the guide column 401, the upper main gear 501 remains tightly meshed with the upper auxiliary gear 502. This design not only ensures that the transmission relationship between the top conveyor belt 2 and the bottom conveyor belt 1 remains unaffected during position adjustments, but also ensures that the conveying speeds of the bottom conveyor belt 1 and the top conveyor belt 2 remain highly consistent through precise gear transmission. Regardless of the material specifications being processed, this ensures that the upper and lower surfaces of the material receive uniform traction force when passing through the cutting traction machine, effectively avoiding material shifting and wrinkling caused by speed differences, and greatly improving cutting accuracy and product quality.

[0032] The cutting traction machine also includes an auxiliary wheel 6. Both sides of the cutting blade 3 are equipped with brackets. The side of the bracket has an opening 13 that is adapted to the auxiliary wheel 6. The auxiliary wheel 6 is rotatably mounted at the opening 13 of the bracket via a rotating shaft, and the outer circumferential surface of the auxiliary wheel 6 is in rolling contact with the side of the cutting blade 3.

[0033] When the cutting traction machine performs cutting operations on materials, the auxiliary wheel 6 plays a crucial role. In various material cutting scenarios, such as cutting paper, film, and leather, the auxiliary wheel 6 rolls along with the cutting blade 3. Because the outer circumference of the auxiliary wheel 6 rolls in contact with the side of the cutting blade 3, it effectively reduces the friction experienced by the cutting blade 3 during movement, making its movement smoother and more stable. Simultaneously, the auxiliary wheel 6 also provides support and guidance for the cutting blade 3, preventing it from shifting or wobbling during cutting, thereby further ensuring cutting accuracy, improving cutting efficiency, and extending the service life of the cutting blade 3.

[0034] Preferably, the inner wall of the bracket is fixedly connected with an auxiliary slide rod 7 extending in the vertical direction, and the side of the cutting blade 3 is provided with a slide groove 8 corresponding to the auxiliary slide rod 7. The auxiliary slide rod 7 and the slide groove 8 cooperate to limit the lifting trajectory of the cutting blade 3 and prevent the cutting blade 3 from shifting laterally during the cutting process.

[0035] In scenarios such as batch cutting of paper in printing plants and fixed-length cutting of plastic film in packaging plants, when the cutting blade 3 moves up and down to perform the cutting action, the auxiliary slide bar 7 slides along the slide groove 8. This restricts the lifting trajectory of the cutting blade 3, ensuring that the cutting blade 3 can only move in the vertical direction and will not deviate laterally. This improves the cutting accuracy and ensures that the cut material dimensions are accurate. At the same time, it also reduces waste caused by the deviation of the cutting blade 3, lowers production costs, and improves production efficiency.

[0036] Preferably, a pad 9 is provided downstream of the material conveying path of the bottom conveyor belt 1 and below the corresponding cutting blade 3, and the upper surface of the pad 9 is flush with the upper surface of the bottom conveyor belt 1.

[0037] During the cutting process, the pad 9 provides stable support for the material to be cut. When the material moves with the bottom conveyor belt 1 to below the cutting blade 3, the pad 9 can withstand the pressure applied by the cutting blade 3, preventing the material from deforming or being damaged due to uneven force, thus ensuring the quality of the cut. Moreover, the upper surface of the pad 9 is flush with the upper surface of the bottom conveyor belt 1, allowing the material to maintain a smooth transition during conveying and cutting, preventing material jamming or tilting due to height differences, further improving the accuracy and stability of the cut.

[0038] In other embodiments, a slide plate 10 can be installed at the feeding end, allowing the product to slide directly off the cutting blade 3. In other embodiments, a cover plate 11 can be installed to protect the internal structure and improve the service life of the cutting traction machine.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
